Still your mind in me, still yourself in me, and without a doubt you shall be united with me, Lord of Love, dwelling in your heart. – Bhagavad Gita
O Krishna, the stillness of divine union which you describe is beyond my comprehension. How can the mind, which is so restless, attain lasting peace? Krishna, the mind is restless, turbulent, powerful, violent; trying to control it is like trying to tame the wind. – Bhagavad Gita
